There is only one type of snake found in Jersey – the grass snake. The grass snake is entirely harmless and the rarest of Jersey’s reptiles.
It is often confused with the slow worm, which is actually a legless lizard.
It is fully protected under the Conservation of Wildlife (Jersey) Law 2000.
What do grass snakes look like?
Adult grass snakes grow to about 80cm long, but can grow as large as 120cm long.
They are a dull green / brown colour, with a cream belly and black markings - black spots and black bars are found down its sides. A lot of grass snakes have a distinctive yellow and black collar, but sometimes this is absent, especially in larger individuals.
Grass snake diet
Grass snakes feed mostly on amphibians (frogs, toads and newts).
Grass snake habitats
Grass snakes are often seen around ponds and streams (they are good swimmers), but can also be found in dry woods, hedgerows and meadows.
They are not just found in wild habitats - they frequently visit gardens and farms.
Grass snakes usually lay their eggs in compost heaps, manure piles and any other warm rotting vegetation.
Where to find grass snakes
Grass snakes are diurnal, which means they're active during the day. The best time to see grass snakes is after they emerge from hibernation in March - April (although they can be encountered until October).
